Hello. I recently ran into a laptop overheating problem. When I checked my task manager, I noticed three WMI Provider Host sessions. Two of them are taking 1% - 2% of CPU, and the third one is devouring out to 30% CPU. I tried to end the process, but it immediately restarts by itself. This problem is causing overheating and lag issues, and my laptop is forced to reboot sometimes. What is this process and why is it taking so much of my CPU power? Is there any solution for this, please? Thanks in advance.
